Want to trade, 338 Lapua DTA barrel, bolt and ammo for the same in 300 prc

[MPNCC]

I have a very low round count (60) 338 Lapua DTA factory 26" barrel. I'd like to move to 300 prc in my DTA.
I have these listed for sure but I believe I have more I just have to dig.
36 S&B 300gr match loads
40 FGMM 300gr loads

If interested let me know
Thanks
